Most of these What Ifs grow out of each other as you will see
#1; what is in OTL known as the Left Opposition rises to power in the 1920is, Trotsky becomes the most powerful person in the Soviet Union
Preobrazhensky becomes one of the people most responsible for economic development
Economy and foreign politics develop accordingly
#2; there are no "Great Purges" instead the OTL pro-Stalinist "Nomenclatura" is dealt with in a few waves of deportations and show trials
The targets of these reduced purges are mostly pro Stalinist functionaries, "politically incorrect" birocrats, a few high ranking officers
High military command and lower ranking officer corps are mostly left alone, most of the urban population, as in the "workers" and the "intellectuals", is also largely unharmed, although there are yailings and a few waves of deportations to Siberia, but nothing near OTL
In the rural areas however, the NKVD is excessively active
#3; Tukhachevsky remains marshal and becomes one of the most influential figures in soviet military
The deep operations doctrine is further developed, and applied with mixed results in the Winter war, and sporadic clashes with the Japanese army
Results are analised and conclusions incorporated into further doctrinal development
Under Tukhachevsky the need for a medium tank is emphasized earlier, and Mihail Koshkin and his team design the T-33 which starts production in late 1939
so to sum up, Trotsky and the "left" are effectively in power, there are no Great purges so the military command and all segments of civilian life are not decimated, Tukhachevsky is marshal and amour development is accelerated, slightly
